This invention relates to improvements in combination teeter totter and merry-go-round.

It is an object of the invention to provide a combination teeter totter and merry-go-round in which one or more boards may be provided to carry two or more passengers either for tilting movement, or rotative movement, or both simultaneously. It is a further object of the invention to provide a readily portable device of this character requiring no permanent mounting and usable in any of a variety of locations to which it may be transported on its own wheels, the wheels providing one of the axes for the tilting movement of the device. Other objects will appear more particularly from the following disclosure.

In the drawings:

Fig. 1 is a view in perspective showing the device embodying the invention.

Fig. 2 is a fragmentary detail view in perspective showing the component parts upon which the upper of the two boards is pivoted to the lower.

Fig. 3 is a fragmentary plan view of the central portion of the device shown in Fig. 1.

Fig. 4 is a view taken in section on the line 4-4 of Fig. 3.

Fig. 5 is a fragmentary view on an enlarged scale in side elevation showing how three boards may be used at 60 angles to each other if desired.

The wheels 6 and 1 support the axle or axle tube 8 from which the brackets 9 carry the board I0. The users are intended to sit at opposite ends of the board l and the provision of the handle posts and handles at H is optional. The wheels 6 and 1 not only provide a convenient means for transporting the apparatus, but they also serve both to provide pivotal mounting on which the board I0 is tiltable and to make the board rotatable bodily as a merry-go-round. If the operators push laterally on either end of the board In, it will be apparent that the board may be bodily rotated about an axis between the wheels 6 and l, the rolling of the Wheels upon the ground accommodating this rotative movement. It will be equally obvious that the board l0 may be tilted on the axis of axle 8 alternatively with or during the rotative merry-go-round movement above described.

Where a separate board is used for additional passengers, it may be identical with board I 0 and set at any desired angle with respect thereto, but the boards should desirably cross at or near their respective centers. For supporting one board from another, I prefer to use the mounting shown in detail in Figs. 2, 3 and 4, including a plate l6 resting on one of the boards and provided with angle brackets l1 between which extends a pintle l8 held at its ends by cotter pins l9 or like means. On this pintle is oscillatable a tubular bearing member 20 having bracket plates at 2| for the other board. If desired, the plate l6 may be omitted and the brackets I l bolted directly to the underlying board as shown in Fig. 4 and Fig. 5.

Fig. 5 shows an additional board 150 identical with board IS, the several boards being symmetrically set at angles so that six passengers instead of four can use the apparatus. While it it broadly possible to provide any desired pivotal mounting of one board from another, the arrangement as disclosed is preferred not only because of its simplicity, but because of its adaptability to a variety of angles as exemplified in Fig. 5. Fig. 5 also shows that either of the transverse boards may be placed beneath, instead of above, the board It], the brackets ll being simply inverted for this purpose.

It is to be observed that by pivoting the secondary boards 15 and IE0 directly upon the primary board It, the oscillatory movement of the primary board It) upon the axle will, result in a lateral tilting of the secondary boards l5 and I50. Such a lateral tilting will enhance the attractiveness of the apparatus by permitting a variation of effect depending upon which of the boards is ridden by one using the apparatus.

I claim:

1. A device of the character described comprising a wheeled axle and a board mounted on the axle for tilting movement with respect to the wheels and for rotary movement about an upright axis between the wheels, in further combination with a plurality of additional boards respectively pivoted upon the first board intermediate the ends of each board, the respective boards crossing each other at acute angles.

2. A combination merry-go-round and teeter totter comprising an axle provided with wheels, board extending across the axle between the wheels, bracket means mounting the board from the axle for tilting movement upon the axis of the axle, and a second board having its intermediate portion pivoted on the intermediate portion of the first board and its ends projecting laterally from the first board.

3. A combination merry-go-round and teeter totter comprising an axle provided with wheels, a board extending across the axle between the wheels, bracket means mounting the board from the axle for tilting movement upon the axis of the axle, and a second board having its intermediate portion pivoted on the intermediate portion of the first board and its ends projecting laterally from the first board, the pivotal connection of the second board with the first board comprising a pair of brackets, a pintle extending between the brackets, a bearing tube oscillatable upon the pintle, the brackets being provided with means bolting them to one of said boards and the bearing tube being provided with means bolting it to the other.
